From Storm Team 2 Meteorologist Chrissy Kohler
Another hot and humid day with highs in the mid 80s to the low 90s. With dew points in the low to mid 70s, the heat index reaches the low 100s in some backyards. The day looks mostly sunny. But by mid afternoon, the risk for thunderstorms increases along the I-95 corridor as a cold front approaches the area. The chance for showers and thunderstorms spreads east through the later part of the day and overnight. A few storms could be strong with the biggest threat being damaging straight line winds. Heavy downpours are also possible but storms should be moving quick enough that the risk for localized flooding is low. However, if heavy rains are falling along the coast around high tide, which is at 9:13 PM in the Charleston Harbor, coastal flooding could be an issue.
Showers and thunderstorms are with us into the day on Sunday. You won’t see rain all day long but the chance for storms is there at any point during the day so be ready to head into doors if you’re planning to be outside. The storms and increased cloud cover keeps temps a bit lower, to highs in the mid to upper 80s. The cold front pushes east Monday but does stall just off shore. So areas away from the coast get a dry but mostly cloudy to partly cloudy day. Whereas along the coast, the stall front brings a continued risk of showers and storms through the day. The front pulls away Monday night making from some drier weather for the middle part of the week.
Behind the front we not only get drier weather, but less humid weather as well a continental high builds in. Morning lows on Tuesday, Wednesday and Thursday are in the mid 60s to the low 70s indicating lower dew points. Afternoon highs are only in the mid 80s. Tuesday looks partly cloudy but a mainly sunny sky returns for Wednesday and Thursday. We return to a more typical summertime pattern late in the week and into next weekend with highs back in the upper 80s to low 90s and a chance for afternoon thunderstorms.
